TECHNICAL FIELD

This invention relates to a solid-state image pick-up apparatus using two line simultaneous read-out type solid-state image sensor in which image pick-up information of all pixels are line-sequentially read out by two lines every one field.

BACKGROUND ART

Hitherto, in order to cope with High Definition (HD) television system such as so called high vision, etc., realization of higher resolution of video cameras is being developed. At the image pick-up (imaging) section of the solid-state image pick-up (imaging) apparatus, as a solid-state image sensor of the Progressive Scan system adapted for reading out image pick-up information of all pixels every field, there is used, e.g., a two line simultaneous read-out type CCD image sensor in which image pick-up information of all pixels are line-sequentially read out by two lines every one field.

This two line simultaneous read-out type CCD image sensor comprises, as shown in FIG. 1, for example, respective vertical transfer register sections VR formed in a vertical direction along light receiving sections P_(O), P_(E) arranged in a matrix form in correspondence with respective pixels, and two horizontal transfer register sections HR₁, HR₂ provided in parallel at the terminating portions of these vertical transfer register sections VR. In this CCD image sensor, respective image pick-up information obtained by the light receiving sections P_(O), P_(E) are transferred independently each other to the two horizontal register sections HR₁, HR₂ by two lines every one horizontal scanning period through the vertical transfer register sections VR, and image pick-up information of all pixels are read out through respective signal output terminals T₁, T₂ from the two horizontal transfer register sections HR₁, HR₂ every one field.

Moreover, in the solid-state image pick-up apparatus using two line simultaneous read-out type CCD image sensor, image pick-up information of all pixels are line-sequentially read out by two lines every one field to form high definition television signals from respective image pick-up signals S_(ODD), S_(EVEN) to output them, or to form a television signal of one channel in conformity with the standard television system such as NTSC system, etc. from respective image pick-up signals S_(ODD), S_(EVEN) by signal processing to carry out additive synthesis through field memory, or the like, thus to output such television signal.

Here, since interlace scanning is employed in the standard television system such as NTSC system, etc., ordinary one line read-out type CCD image sensor is adapted to cope with the above-mentioned interlace scanning in a manner as described below.

Namely, in the frame storage mode where charge storage (time) period of each light receiving section is caused to be one frame (time) period, an approach is employed to read out image pick-up charges obtained at light receiving sections of odd lines as image pick-up output of odd field, and to read out image pick-Up charges obtained at light receiving sections of even lines as image pick-up output of even field to thereby obtain an interlaced image pick-up output. Moreover, in the field storage mode where charge storage (time) period of each light receiving section is caused to be one field (time) period, an approach is employed to additively mix image pick-up charges obtained at light receiving sections of odd lines and image pick-up charges obtained at light receiving sections of even lines to read out them to switch, in upper and lower directions, lines to be added every one field to thereby obtain an interlaced image pick-up output.

As stated above, in ordinary CCD image sensor adapted to cope with interlace scanning, it is impossible to allow resolution with respect to object having movement (motion), i.e., dynamic resolution to be high.

In view of this, in industrial image pick-up apparatuses adapted for imaging (image-pick up), as still picture, object mounted on a transfer body such as a belt conveyer, etc., stroboscope, mechanical shutter or electronic shutter function of CCD image sensor is used to ensure higher dynamic resolution.

Meanwhile, in the solid-state image pick-up apparatus using two line simultaneous read-out type CCD image sensor, if there is employed an approach to form high definition television signals from respective image pick-up signals S_(ODD), S_(EVEN) in which image pick-up information of all pixels are line-sequentially read out by two lines every one field, high speed signal processing is required for forming high definition television signal. Moreover, if there is employed an approach to output such television signal as a television signal of one channel in conformity with the standard television system, one frame (time) period is required for outputting image pick-up information of all pixels.

Further, image pick-up output by industrial image pick-up apparatus permits implementation of picture processing of high accuracy by using image pick-up information of all pixels of one frame.

In addition, while no interlaced image pick-up output is required in industrial image pick-up apparatuses in which image pick-up pictures are processed by computer, those apparatuses are caused to handle television signals in conformity with the standard television system to thereby permit employment of general devices for peripheral equipment or interface, thereby making it possible to easily construct system.

In view of actual circumstances as described above, an object of this invention is to provide a solid-state image pick-up apparatus suitable as an industrial image pick-up apparatus, which is capable of outputting image pick-up information of all pixels of one frame within one field period.

Another object of this invention is to provide a solid-state image pick-up apparatus which can form standard television signals of 2 channels from respective image pick-up signals by the two line simultaneous read-out type solid state image sensor to output such standard television signals.

A further object of this invention is to provide a solid-state image pick-up apparatus capable of outputting, as non-interlaced television signals of 2 channels, respective image pick-up signals of fields different from each other which have been simultaneously read out by 2 lines from the two line simultaneous read-out type solid-state image sensor.

A still further object of this invention is to provide an imaging system suitable for industrial purpose which can output, within one field time period, image pick-up information of all pixels of one frame.

BEST MODE FOR CARRYING OUT THE INVENTION

Preferred embodiments of a solid-state image pick-up apparatus according to this invention will now be described with reference to the attached drawings.

The solid-state image pick-up apparatus according to this invention is constituted as in the first embodiment shown in FIG. 2, for example.

The solid-state image pick-up apparatus of the first embodiment shown in FIG. 2 comprises an imaging section 10 comprised of 2 line simultaneous read-out type CCD image sensor 11, a correlative double sampling processing section 20 composed of first and second correlative double sampling circuits 21, 22, a process processing section 30 composed of first and second process processing circuits 31, 32, a signal output section 40 composed of first and second output amplifiers 41, 42, and a drive control section 50 composed of first and second synchronizing signal generators 51, 52, a CCD drive circuit 53, a crystal oscillator 54 and a timing generator 55, etc., whereby an approach is employed to drive and control, by the drive control section 50, the imaging section 10, the correlative double sampling processing section 20 and the process processing section 30 to thereby form standard television signals S_(OUT1), S_(OUT2) of 2 channels formed by the process processing section 30 with respect to respective image pick-up signals S_(ODD), S_(EVEN) which have been simultaneously read out by 2 lines from CCD image sensor 11 of the imaging section 10 to output these standard television signals S_(OUT1), S_(OUT2) of 2 channels from first and second output terminals 61, 62 through the signal output section 40.

In the solid-state image pick-up apparatus of the first embodiment, CCD drive circuit 53 of the drive control section 50 forms various CCD drive pulses such as signal charge read-out pulse, horizontal transfer pulse, vertical transfer pulse, electronic shutter pulse, etc. on the basis of timing pulse for CCD drive delivered from timing generator 55 to deliver these CCD drive pulses to CCD image sensor 11 of the imaging section 10.

The 2 line simultaneous read-out type CCD image sensor 11 constituting the imaging section 10 is driven by the CCD drive circuit 53, and is operative in the odd field as shown in FIG. 3 to output, as image pick-up signal S_(ODD), respective image pick-up information obtained by light receiving sections P_(O) of odd lines from first output terminal 12, and to output, as image pick-up signal S_(EVEN), respective image pick-up information obtained by light receiving sections P_(E) of even lines from second output terminal 13. Moreover, as shown in FIG. 4, in the even field, the CCD image sensor 11 is operative to sweep away image pick-up information of the first 1 line obtained by light receiving section P_(O) of even line thereafter to carry out 2 line simultaneous read-out operation to thereby output, as image pick-up signal S_(EVEN), respective image pick-up information obtained by light receiving sections P_(E) of even lines from first output terminal 12, and to output, as image pick-up signal S_(ODD), respective image pick-up information obtained by light receiving sections P_(O) of odd lines from second output terminal 13. Namely, as shown in FIG. 5, the CCD image sensor 11 reads out all pixel information every field to alternately output image pick-up signal S_(ODD) of odd line and image pick-up signal S_(EVEN) of even line from first and second signal output terminals 12, 13.

Image pick-up signals S_(ODD) /S_(EVEN) alternately outputted every field from first signal output terminal 12 of the CCD image sensor 11 are delivered to first correlative double sampling circuit 21 of the correlative double sampling processing section 20, and image pick-up signals S_(EVEN) /S_(ODD) alternately outputted every field from second signal output terminal 13 of the CCD image sensor 11 are delivered to second correlative double sampling circuit 21 of the correlative double sampling processing section 20.

The correlative double sampling processing section 20 is operative to carry out processing to respectively clamp, with respect to respective image pick-up signals S_(ODD) /S_(EVEN), S_(EVEN) /S_(ODD) which have been simultaneously read out by two lines through the first and second signal output terminals 12, 13 from the CCD image sensor 11, on the basis of sample hold pulse delivered from timing generator 55 of the drive control section 50, reset noise levels by the first and second correlative double sampling circuits 21, 22 to sample and hold output levels with the clamped reset noise level being as reference to thereby reduce reset noise. The image pick-up signals S_(ODD) /S_(EVEN) in which reset noise has been reduced by the first correlative double sampling circuit 21 are delivered to first process processing circuit 31 of the process processing section 30, and image pick-up signals S_(EVEN) /S_(ODD) in which reset noise has been reduced by the second correlative double sampling circuit 22 are delivered to second process processing circuit 32 of the process processing section 30.

The process processing section 30 serves to carry out signal processing for forming standard television signals of 2 channels from respective image pick-up signals S_(ODD) /S_(EVEN), S_(EVEN) /S_(ODD) in which reset noise has been reduced by the correlative double sampling processing section 20. Namely, first process processing circuit 31 of the process processing section 30 implements, with respect to image pick-up signals S_(ODD) /S_(EVEN) in which reset noise has been reduced by the first correlative double sampling circuit 21, on the basis of blanking pulse and/or synchronizing signal delivered from first synchronizing signal generator 51 of the drive control section 50, signal processing such as gain up, pedestal set, white clip, blanking cleaning and addition of synchronizing signal, etc. to thereby form television signal S_(OUT1) in conformity with the standard system (e.g., NTSC system). Moreover, second process processing circuit 32 implements, with respect to image pick-up signals S_(EVEN) /S_(ODD) in which reset noise has been reduced by the second correlative double sampling circuit 21, on the basis of blanking pulse and/or synchronizing signal delivered from second synchronizing signal generator 52 of the drive control section 50, signal processing such as gain up, pedestal set, white clip, blanking cleaning, and addition of synchronizing signal, etc. to thereby form television signal S_(OUT2) in conformity with the standard system (e.g., NTSC system).

Here, first and second synchronizing signal generators 51, 52 of the drive control section 50 become operative by common system clock given by the timing generator 55, and are operative as shown in FIG. 6 at the timing where timings of horizontal synchronization HD are the same and timings of vertical synchronization VD are shifted by H/2. These generators 51, 52 respectively deliver blanking pulse and synchronizing signal to first and second process processing circuits 31, 32 of the process processing section 30.

Then, in the process processing section 30, standard television signals S_(OUT1), S_(OUT2) of 2 channels formed from respective image pick-up signals S_(ODD) /S_(EVEN), S_(EVEN) /S_(ODD) are outputted from first and second output terminals 61, 62 through first and second output amplifiers 41, 42 of the signal output section 40.

In this example, first and second output amplifiers 41, 42 of the signal output section 40 have output impedance of 75 ohms matching with the characteristic impedance of transmission cables respectively connected to the output terminals 61, 62.

In the solid-state image pick-up apparatus of the first embodiment thus constituted, since there is employed an approach to form, from image pick-up signal S_(ODD) of odd line and image pick-up signal S_(EVEN) of even line alternately outputted every field through two signal output terminals 12, 13 of the 2 line simultaneous read-out type solid-state image sensor 11, standard television signals S_(OUT1), S_(OUT2) of 2 channels by first and second process processing circuits 31, 32 to output the standard television signals S_(OUT1), S_(OUT2) of 2 channels from output terminals 61, 62, it is possible to output all pixel information of the solid-state image sensor 11 every field.

Accordingly, as shown in FIG. 7, for example, in an imaging system in which picture processing unit 80 is connected to the solid-state image pick-up unit (apparatus). 70 according to this invention, the standard television signals S_(OUT1), S_(OUT2) of 2 channels are taken into field memory sections 81, 82 every field, thus making it possible to carry out picture processing using all pixel information of the solid-state image sensor 11 by picture processing section 83. Moreover, since image pick-up output signals S_(OUT1), S_(OUT2) of 2 channels outputted from the output terminals 61, 62 are respectively television signals in conformity with the standard system, one side channel is utilized, thereby making it possible to conduct monitoring by monitor unit 90. This is convenient in determination of picture angle (angle of view) of picture and/or positioning thereof.

The imaging system shown in FIG. 7 serves to image (image-pick up) object transferred (conveyed) on carrying path by the solid-state image pick-up unit 70 to carry out picture processing by picture processing unit 80 with respect to that image pick-up output. In more practical sense, object sensor for detecting passing of object is provided at the upstream side of the carrying path to drive, by synchronization control unit supplied with detection signal of the object sensor strobe emitting unit at the timing where the object falls within the image pick-up range of the solid-state image pick-up unit 70, thus to strobe-image the object. Further, memory control signal R/W_(CTL) is delivered from the synchronization control unit to the picture processing unit 80 to take the standard television signals S_(OUT1), S_(OUT2) of 2 channels into field memory sections 81, 82. Further, picture data of one frame using all pixel information of the solid-state image sensor 11 is generated by the picture processing section 83 thus to carry out picture processing.

Here, field memory section 81 in the above-mentioned picture processing unit 80 comprises, as shown in FIG. 8, for example, synchronization separating circuit 81a for separating synchronizing signal added to standard television signal S_(OUT1) delivered from the solid-state image pick-up unit 70, timing generator 81b for generating timing pulses synchronous with synchronizing signal obtained by the synchronization separating circuit 81a, A/D converter 81c for digitizing the standard television signal S_(OUT1) in accordance with timing pulse delivered from the timing generator 81b, and field memory 81d into which standard television signal S_(OUT1) digitized by the A/D converter 81c is written, whereby write processing synchronous with synchronizing signal added to the standard television signal S_(OUT1) is carried out. Similarly, field memory section 82 in the picture processing unit 80 comprises synchronization separating circuit 82a for separating synchronizing signal added to standard television signal S_(OUT2) delivered from the solid-state image pick-up unit 70, timing generator 82b for generating timing pulse synchronous with synchronizing signal obtained by the synchronization separating circuit 82a, A/D converter 82c for digitizing the standard television signal S_(OUT2) in accordance with timing pulse delivered from the timing generator 82b, and field memory 82d into which standard television signal S_(OUT2) digitized by the A/D converter 82c is written, whereby write processing synchronous with synchronizing signal added to the standard television signal S_(OUT2) is carried out.
